INVESTIGATION OF SOIL-STRUCTURE INTERACTION OF BURIED CONCRETE PIPE
A long-range research project has been undertaken to investigation the nature of the loading imposed on a concrete pipe when it is buried at a significant depth below the surface of the ground. The project consists of (a) a series of field installations and (b) development of a comprehensive finite-element program. The initial field tests consisted of a trench installation and an embankment installation. Pipe sections were instrumented with strain gauges, fittings for taking diameter and chord measurements, and surface pressure meters. Stress cells were installed in the soil at various locations in the vicinity of the pipe. Data will be used to verify the accuracy of the computer simulation. The plane strain computer model will permit the use of nonlinear mechanical properties for both concrete and soil materials. A cracking mechanism has been developed that accurately modesl the behavior of concrete pipe at the initiation of, and following the development of, cracking in the concrete. The validity of the finite-element model of the pipe has been established on the basis of the results of a program of laboratory tests on sections of a full-size concrete pipe under controlled loading conditions. The proven computer model of the soil-structure system will help to make it possible to identify the relative significance of various parameters of the interaction system.
